SPECIFICATION forming part of Letters Patent N o. 744,082, dated November 1'?, 1903. Apprenti nei January ci, 190s. serial No. 141.344. in@ maar To a/ZZ whom it may concern:

Beit known that I, RICHARD J AMEs Lons, a citizen of the United States, residing at Coxville, in the county of Parke and State of In diana, have invented a new and useful Stove- Grate, of which the following is a specification.

This invention relates generally to stoves and furnaces, and more particularly to an improved construction of grate adapted for use in connection with the ordinary cylinder or barrel stove; but it will be distinctly understoodl that the said grate can be used equally as Wellin a latrobe andalso in a furnace, if so desired.

The object of the invention is to provide a simple construction of grate, which will support the coal to be burned in the fire-pot and which will hold the live coals which' are shaken through the grate for a certain length of time before depositing them into the ashchamber. Y v Y Another object is to provide a grate which can be adjusted so as to regulate the draft o air passing therethrough.

With these objects in view the invention consists in the novel features of construction, combination, and arrangement, all of which will be fully described hereinafter and pointed out in the claims. y

In the drawings forming part of this specilication, Figure 1 isa vertical sectional view showing the lower portion of a stoveprovided with a grate constructedin accordancewith my invention. Fig. 2 is a topplan view of the grate. Fig. 3 is a detail perspective view of the cylinder, in which the grate is arranged. Fig. 4 is a detail perspective view illustrating the upper and lower sections of the grate.A Figs. 5, 6, and 7 show details of construction.

AReferring to the drawings, A indicates the shell of an ordinary stove, B the iire-pot, and C the ash-chamber. The nre-pot B rests upon a ring or flange D, and a short distance below the said ring or ilange is a second ring or flange E, and bolted to the flanges D and E and arranged between the saineY is a cylin- .der F, having an outward ly-proj ectin g iiange F' at its upper and lower ends, by means of which the said cylinder is securely bolted to the said rings or iianges D and E. This cylinderF may be made any length desired, ac

vcording to the contruction of the stovewithin which it is to be arranged. This cylinder F is intended to carry the grate, which comprises the upper section G and the lower section H, which are connected by means of a'shaft I and are operated by means of a hand-`lever K, rigidly connectedv to the lower end of the shaft'l and having its outer end projecting 6o through a horizontal slot produced in the shell of the stove. The upper section of the grate comprises two plates G and G2, and the lower section consists also of two plates H and H2. The plates G and G2 have openings G8 pro- 65 duced therein, and the plates H and H2 have openings H3 produced therein. The plate G2 has projections G4, which are adapted to tit into recesses F2, produced in the cylinder F,

adjacent to the upper end thereof, and the 7o -plate H' is also provided with projections H4,

which are adaptedto fit into recesses F3, produced in the sides of the cylinder adjacent to the lower end. The shaft I is formed with a collar I adjacent to the upper end, and directly above the said collar is the round portion l2, and above that the square portion 1B. The plate G2, having a central circular opening, is tted upon the shaft so that the round portion Izwill occupy the cen- So tral circular opening of the said plate, and the plate G has a square central opening G5, which lits upon` the square portion I3 of the shaft I, and a nut GrG is screwed upon the reduced threaded end of the shaftv for the purpose of securely fastening the parts together. The plate H hasa central circular opening which fits on the circular portion of the shaft I, and the plate H2 has a central square opening H5, which ts upon the square portion I5 9o of thershaft, and the inner end of the operating-lever K isalso fastened upon said square portion and a nut 1G employed' to secure said parts together. The plates G and G and H and H' are so arranged with reference to each 95 other that when the openings of one pair of plates are brought into register the openings 'of the otherpair of plates are thrown out of means of this construction when it is desired to dump a portion of the live coals from the fire-pot the hand-lever is turned around so as to open the openings in the top section of the grate and close the openings in the lower section, 'and in this way the live coals so dumped will be held within the grate any desired 4length of time before being finally dumped into the ash-chamber C. Furthermore, by turning the hand-lever so as to open one set of openings and partially close another set of openings the desired amount of draft passing through the grate can be regulated to a nicety. It will also be noted that the plates of each pair are arranged close together, so as to prevent ashes or live coals getting between said plates and interfering with the movement thereof, and inasmuch as one plate of each pair is held stationary the manipulation of the grate is rendered much easier.

Having thus fully described my invention, what I claim as new, and desire to secure by .Letters Patent, is-

lever adapted to actuate the movable plates simultaneously.

2. A stove grate comprising a cylinder adapted to be arranged in a stove or furnace, said cylinder having a grate-section at each end thereof, each grate-section consisting of two plates arranged close together, each plate havingaplurality of openings produced therein, a shaft for connecting the movable plates and means for turning said movable plates so as to bring the openings into and out of register, as specified.

3. A stove-grate comprisinga cylinder, having recesses at its upper and lower end, of plates having openings produced therein, said plates being arranged in pairs, one plate of each pair having projections adapted to fit into the recesses produced in the cylinder, a shaft arranged centrally of the said plates, one plate of each pair being rigidly connected to the said shaft, and the operating -lever connected also to the shaft whereby the plates rigid with the shaft can be turned for the purpose of bringing the openings in the plates into and out of register.
